You have to distinguish two ways the postrm is being called: * postrm remove (at this point the dependencies are still available) * postrm purge (at this point the the dependencies may have been long gone) > How is the installation done in piuparts ? install depends(package) install package remove package remove depends(package) purge depends(package) purge package That's the worst-case purge ordering. > The removal below shows dpkg being invoked directly.
